FASTENER.

Application filed March 8, 1921. Serial No. 450,747.

To all w 7mm it may concern:

Be it known that I. FRED CARR, a citizen of the United States, and a resident of Newton, in the county of Middlesex and Con inonwealt-h of llllassachusetts, have invented an Improvement in Fasteners. of which the following description, in conne-.;tion with the accompanying drawings, a specification. like characters on the drawings representing like parts.

This invention pertains to improvements in separable fasteners. lit is among the objects of the invention to provide a stud and socket fastener ofsimple and rugged construction having superior holding power.

In the drawings, which'show a preferred embodiment of one illustrative form of my invention: 1

Figure 1. is an elevation of the fastener in which the stud and socket are secured to their carrying fabrics;

Fig. 2 is a section on the line 2-2 of Fig. 1

Fig. 3 is a front elevation of the socket illustrated in Figs. land 2; and

Fig. 1 is a front elevation of the stud il-- lustrated in Figs. 1 and 2.

Referring to the drawings and the preferred form of my invention selected for illustrative purposes, I have shown astud having a head 5, neck 6 and a base flange 7 secured by stitching to a stud-carrying fabric 8 in the usual manner. The preferred form of socket illustrated includes a casing 9, presenting a peripheral wall 10, and flanges 11 and 12 lying on opposite sides of spring 13 which is preferably, as illustrated, formed of sheet metal. and which may resemble somewhat that illustrated in my co-pending application Serial No. 450,749, filed herewith. The spring 13, as illustrated, presents a stud-receiving aperture 14 and is preferably slotted at 15 from said aperture to the periphery of the sprin The spring may provide stitch-receiving apertures 16, preferably three in number, and preferably arranged about the studreceiving aperture in the same manner as described in my co-pending application above referred to. The flange 12 may be perforated opposite the stitch-receiving apertures in the spring. I preferably provide means on the casing for limiting a resilient opening of the spring, this means in the illustrative form of my invention taking the form of bosses 18, 19, thrown up on oppositesides of those portions of the spring adjacent the slot 15, which also serve as means opposing turning of the spring in the casing. The spring is preferably notcoed at 20, this being that side of the stitchreoeiviug aperture toward the slot The socket is preferably applied to its carrying fabric in such a way that when the stud is engaged therewith the normal line of strain will be toward the slot in the spring. The spring may be and. preferably is slotted at 21, 21, 21 between the stud-receiving aperture 1 1 and the stitch-receivingapertures 16.

When the stud is entered in the socket, the spring expands, and when the head of the stud has passed. the spring, the latter contracts again. When lateral strain is ex erted between stud and socket in a direction toward that portion of the spring which is slotted to its periphery, there may be a tendency for the spring to expand and release the head of the stud,,but this tendency is overcome by reason of the support given the spring by the casing, the support in the preferred construction illustrated being the projections from the casing at either side of that portion of the spring adjacent the slot which extends to the periphery of the spring. The attachment of the socket preferably is such as to leave that side of the socket in the direct line of strain unattached, and where three attaching points are used, as in the preferred embodiment of my invention illustrated, these should preferably be substantially equi-distant from the axis of the stud-receiving aperture of the spring.

l Vhile I have shown and described a preferred form of one embodimentof my invention, it will be understood that changes involving omission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.

Claims.

1. A socket for snap fasteners comprising, in combination, a casing, and a sheet metal spring in said casing, said spring presenting a stud-receiving aperture and split at one side to provide resiliency, and means on said casing limitinig resilient opening of said spring.

A socket for snap fasteners comprising, in combination, a casing, and a sheet in combination, a casin metal spring in said casing, said spring presenting a stud-receiving aperture and split at one side to provide resiliency, and means on said casing limiting resilient opening'ofsaid spring, said spring notched at one side of said opening.

3. A socket for snap fasteners comprising, and a sheet metal spring in said casing, said spring presenting a stud-receiving aperture andsplit at one side to provide resiliency, and means on said casing); limiting resilient opening of said spring, said spring notched at one side of said opening adjacent the split in said spring".

4;. A socket for snap fasteners compris ing, in combination, a casing, and a sheet metal spring in said casing, said spring presenting a stijid-ii'eceiving aperture and split at one side to provide resiliency, and. means on said casing limiting resilient opening of said spring, said spring notched at one side of said opening between. said means on said casing.

5. A socket for snap fasteners comprising, in combination, a casing, a sheet metal spring in said casing, means opposing turning movement of said spring in said casing, a stud-receiving aperture in said spring and stitch-receiving"apertures in said socket at threesides of said stud-receiving aperture, tl'lHfOillthl adapted to be left unstitched to the socket-carrying fabric.

6. A socket for snap fasteners comprisin in combination, a casing, a sheet metal spring in said casing, means opposing turningmovement of said spring in said casing, a stud-receiving aperture in said spring and stitch-receiving apertures in said socket at three sides of said stud-receiving aperture, the fourth adapted to be left unstitched to the socketmarrying fabric, the stitch-receiving apertures equi-distant from the axis of the stud-receiving aperture.

7. A socket'for snap fasteners comprising, in combination, a casing, a sheet metal spring in said casing, 1neans opposing turning movement of said spring in said casing,

a stud-receiving aperture in said spring and stitch-receiving apertures in. said socket, the stitch-receiving apertures equidistant from the axis of the stud-receiving aperture but inisynnnetrically disposed thereabout the side of said socketin the line of strain When in use presenting no stitch-receiving aperture.

8. A socket for snap fasteners comprising", in combination, a casing, a sheet metal spring in said casing, means opposing, turning movement of said spring in said casing, a stud-receiving aperture in said spring and stitch-receiving apertures insaid'socliet,said "titch-receiving apertures passing through said spring. v

In testimony whereof, I have signed my name to this specification.
